Found the answer - I needed to install lxsession-edit, and that gives me
the "Policykit Authentication Agent" tickbox. Now all is well.
One oddity though: on a fresh install of Lubuntu 18.04, everything works
as expected - yet the Policykit Authentication Agent box is
unchecked... Can anyone
This looks like the problem I have in Lubuntu 18.04 (but only in systems
upgraded from 16.04 - new installs seem fine).
But I can't find the magic "Policykit Authentication Agent" tickbox in
Lubuntu: where is it hiding?

By the way, I find this is a transient issue. It went away after a
reboot, but perhaps it'll come back after enough suspend/resume cycles,
or on some subsequent reboot. Again, smells like a race condition.

(I am using XFCE in German, so maybe the wording I describe here is not 100%
accurate)
In the XFCE settings menu - Session management - Automatically started

This was unchecked. Re-check,
After the last update to policykit-1-gnome 0105-1ubuntu3.1, nothing
better. Concerning bugs around policykit-1-gnome, I hoppened a bug

It has turned out that the problem affects more components than I
originally noticed:
